Leiomyosarcoma: a 45-year review at Charity Hospital, New Orleans.
Approximately 2 to 9% of all soft tissue sarcomas are leiomyosarcomas (LMS). LMS arises nearly exclusively as tumors in adults, with peak incidence occurring in the fifth and sixth decades. The purpose of this study was to analyze disease-specific survival and define prognostic factors in patients with this disease who were treated and followed at a single institution. Fifty-eight cases of LMS were identified in the Tumor Registry of the Medical Center of Louisiana at New Orleans (charity Hospital) from 1950 to 1995. Charts were reviewed and tissue blocks reexamined to confirm the diagnosis. Follow-up information was available for 56 of 58 (96%) patients. Univariate and multivariate analyses were performed to analyze which factors predict outcome. The median survival time was 138 months. Univariate analysis identified age (> 48 years), location (retroperitoneal vs other sites), and extent of disease as prognostic factors. Multivariate analysis revealed that only age and the extent of disease at presentation are independent prognostic indicators. Race, sex, and adjuvant therapy were not significant prognostic factors. Surgical resection remains the therapeutic mainstay for patients with LMS. The value of other treatment modalities is largely limited to surgical failures. The data show that the age of the patient and the extent of disease at presentation are the best predictors of long-term survival. LMS has a good prognosis when complete resection of localized lesions can be achieved.
